Good app and product, but have a request

I like the camera and the app. I have a couple similar products from competitors and a professional model as well. The image processing is very nice and the high refresh rate is a great feature. The request I have, however, is to please allow separate font colors for the high and low temperature readings. And also allow a larger font. It’s is difficult to pick one color that is easy to read against both hot and cold targets. Otherwise no other issues so far.

Easy to download and install, once I opened the app and plugged my top Don tcview infrared camera with the extension cable, my phone asked me to put in my password and it took a second for it to recognize the device and it started working. Quite simple. I guess somebody who has had issues with this needs to clean their charge port.
